FENCE-RIVETING MACHINE.

SPECIFICATION forming part of Letters Patent No. 403,950, dated May 28,1889.

Application filed March 16, 1889. Serial No. 303,585. (No model.)

To all whom, it may cmwcrn:

Be it known that 1, WILLIAM WATERMAN MCOALLIP, a citizen of the UnitedStates, residing at Columbus, in the county of Franklin and State ofOhio, have invented new and useful Improvements in Riveting-Machines, ofwhich the following is a specification.

My invention relates to improvements in riveting-machines especiallyadapted for riveting pickets to the rails or bars of an iron fence; andit consists in the peculiar construction and combination of devices,that will be more fully set forth hereinafter, and particularly pointedout in the claims.

In the accompanying drawings, Figure 1 is an elevation of ariveting-machine embodying my improvements, showing the manner of usingthe same. Fig. 2 is a top plan view. Fig. 3 is a crosssection taken onthe line at a: of Fig. 2. Fig. 4 is a detail cross-section on the line 3y of Fig. 2.

On a bench or frame, A, which has suitable supporting-legs, B, is bolteda plate, 0, having a pair of standards, D, the latter forming thebearings for the pivotal bolt or trunnions E of a beam, F. To one end ofthe latter is secured a hammer-head, G, with its lower end fashioned asshown in Fig. 3. The front end of the hammer-beam moves between a pairof vertical guides, H H, and suitable mechanism of any well-known kindmay be employed Such mechanism, however, has not been shown in thedrawings,

inasmuch as it forms no part of the present invention. In rear of thefulcrum of the hammer-beam and suitably connected with the latter isarranged a coiled spring, the expansive force of which aids the hammerin delivering its blows.

On the front end of the frame A is arranged a guide-frame, whichcomprises a pair of vertical bars, 0, having vertical slots P. To theupper ends of the said bars are attached supporting-brackets R, overwhich the metallic fence bar or rail a is adapted to be moved. Saidfence bar or rail is of the usual construe tion and is rolled with theusual longitudinal groove, b, and is provided with the usual openings,0, arranged at suitable distances apart and adapted to receive thetenoned ends of the rods cl.

A pair of guide-bars, S, are secured at reguthe latter to the rail a.

lar distances apart by blocks inserted in their ends, and adjListing-bolts T pass through the ends of said bars and are adapted tomove in the slots P. The function of the said bars is to steady andretain the rods d against lateral movement while the same are beingriveted in the openings 0.

Under the guide-bars S and in Vertical alignment with the hammer is ablock, U, which has a vertical opening adapted to receive the lower endof the spindle of a diereceiver, V. A set screw, WV, works in a threadedopening in a collar, X, on the upper side of the block and engages thedie-receiver, serving to retain the latter at the correct verticaladjustment. The upper end of the diereceiver is dovetailed to receivethe transversely-slidin g die Y, the latter having an opening or recess,Z, which may be placed a suitable distance out of alignment verticallywith the hammer, as indicated in Fig. 1. Said die-is retained in placein the die-receiver by a set-screw, A, and may be removed and reversedor replaced by another when desirable.

A horizontal supporting-rail, B, has one end attached to one of thestandards 0, and has its opposite end supported by a suitable standard,0, and on the said rail travels a grooved wheel, 13*, from the pivots oraxis of which is suspended a carriereframe, E, the latter being adaptedto support one end of the rail a, and hence enable the latter to beeasily moved on the bracket R, so that each opening 0 will successivelyregister with the hammer.

The operation of my invention is as follows: A workman inserts each bard in succession with its lower end in the die and its upper tenoned endin one of the openings 0, thereby arranging the said bar d at an angleother than a right angle to the rail or bar a, as shown in Fig. 1. Thehammer is operated, and the same serves to swage the tenoned end of thebar (1, and thereby securely fasten The bars (1 from the center to theends of the rail a are inclined in opposite directions, as indicated inFig. 1, and when the said rods (1 are arranged parallel with each other,which is done when the other fence-rails are placed in position thereon,the bottom rail, a, will become arched, as is apreceiver, all incombination, substantially as parent, and thereby adapted to withstand agreater vertical strain, and thus prevent the fence panels from sagging.

Having thus described my invention, I claim- 1. In a machine forriveting iron fences, the combination of the hammer, the die arrangedout of vertical alignmenttherewith, the guideframe to support one end ofthe fence bar or rail, and the traveling carrier to support the otherend thereof, substantially as described.

2. The combination, in an iron-fence-rivet ing machine, with the hammer,of the supporting-frame having the armor bracket R, for the purpose setforth, the guide-bars S, vertically adjustable on said frame, and thedie,substantially as described.

3. -;'lhe-combination,'with the hammer, of;

the block U,'arranged below the same, the{ die-receiver supportedin theblock, and the die fitted adj'ustably in a recess in the upperi; end ofthe receiver, substantiallyas describedj 4. The block U, having thevertical recess; and collar X, with set-screw W, the die-re-iceiverhaving the spindles'in said opening or; recess and; engaged by theset-screw, "and the; dieflfitted in the recess in the upper end of the?described. 1 j

5. The rail'ct and the bars or rods d, with one end secured thereto,said rods being inin said recess and having an opening or reccss in itsupper face, and a fastening-screw, substantially-as set forth.

8. The combination of the hammer, the anvil havinga dovetailed recess,the trans verselyadjustable die having a recess in its upper-face, andmeans for suspending and carrying the fence-rail transversely under thehammer-and for guiding the pickets,=substantially as set forth.

In testimony that'l claim the foregoing as my own I h-avehereto affixedmy signature in .presence of two'witnesses.
